Abstract
Torsional pendulum moment of inertia measuring instrument angle controller described in the utility model mainly comprises gag lever post, connecting link, connecting link is sleeved on the newel of torsional pendulum moment of inertia measuring instrument, can slide up and down, also can rotate arbitrarily around newel, be fixed on newel by screw, gag lever post is fixed on connecting link, and the top of gag lever post is higher 0-10 millimeters than the bar that is in the light of horizontal positioned, and gag lever post screw (6) regulates the high and low position of gag lever post (2).During use, regulate connecting link fixed position on centre post, make to be in the light when bar rotates 90 degree from rest position and just contact gag lever post, ensuing each measurement, only the bar that is in the light need be forwarded to after gag lever post place contacts with gag lever post and unclamp, identical and equal 90 degree with regard to each angle of initially rocking can be ensured.
Description
Technical field
The utility model relates to Experiment of College Physics torsional pendulum moment of inertia measuring instrument, relates generally to the restricted problem of the initial angle rocked.
Background technology
Torsional pendulum type rotation inerttia instrument is the physical experiment apparatus that a kind of a lot of colleges and universities offer.In order to energy Measurement accuracy moment of inertia, it is one of fundamental that the initial angle rocked controls at 90 degree.Operator is relied on now to estimate to grasp the initial angle rocked completely, variant between different operators, also variant between each operation of same operator.This will bring error to measurement result.
Summary of the invention
In order to when accurately controlling rotation inerttia rock initial angle be 90 degree and each angle identical, the utility model devises a kind of torsional pendulum moment of inertia measuring instrument angle controller.
Torsional pendulum moment of inertia measuring instrument angle controller described in the utility model mainly comprises gag lever post, connecting link, connecting link is sleeved on the newel of torsional pendulum moment of inertia measuring instrument, can slide up and down, also can rotate arbitrarily around newel, be fixed on newel by screw, gag lever post is fixed on connecting link, and the top of gag lever post is higher 0-10 millimeters than the bar that is in the light of horizontal positioned, and gag lever post screw (6) regulates the high and low position of gag lever post (2).During use, regulate connecting link fixed position on centre post, make to be in the light when bar rotates 90 degree from rest position and just contact gag lever post, ensuing each measurement, only the bar that is in the light need be forwarded to after gag lever post place contacts with gag lever post and unclamp, identical and equal 90 degree with regard to each angle of initially rocking can be ensured.
The beneficial effects of the utility model are the initial angles that can ensure to rock is 90 degree, and each measure initially to rock angle identical, be conducive to the measuring accuracy improving moment of inertia.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the scheme of installation of torsional pendulum moment of inertia measuring instrument angle controller.
Fig. 2 is in the light bar when turning over 90 degree from rest position and the firm accessible schematic diagram of gag lever post.
In figure, 1, be in the light bar, and 2, gag lever post, 3, connecting link, 4, screw, 5, newel, 6, gag lever post screw.
Embodiment
In fig. 1 and 2, connecting link (3) is sleeved on the newel (5) of torsional pendulum moment of inertia measuring instrument, can slide up and down, also can rotate arbitrarily around newel, fixed by screw (4), gag lever post (2) is fixed on connecting link (3), the top 0--10 millimeter higher than the bar that is in the light (1) of horizontal positioned of gag lever post (2), gag lever post screw (6) regulates the high and low position of gag lever post (2), gag lever post (2) and the fixed position of connecting link (3) on centre post (5) make to be in the light when bar (1) rotates 90 degree from rest position just to contact gag lever post (2).
Claims (2)
